Issue
On a MNL-800 controller, are resistors required on the universal inputs when wired for pulse counting?
Environment
MNL-800 controller
Cause
Knowing the resistor requirement helps implementing pulse count using universal inputs.
Resolution
UI1 does not require an external resistor. If using UI2 through UI8 as a pulse input, an external 10K resistor to +5.1 V is required.
